To help correct the rear driveshaft angle by leaving the stock crossmember in the stock location, these motor mounts work great. They also work with the TeraFlex BellyUp crossmember. These motor mounts are the same as our standard "BombProof" mounts, except that they are designed to "Lift" the engine one inch.
Offroading seriously in your Jeep places undue stress on stock components they were never designed to handle. With deep gearing, big tires, lockers, and mega torque, the stock mounts can be torn apart in no time at all. That's where the Mountain Offroad "BombProof" motor mounts come into play. They bolt into stock holes in the frame and engine. Most application do not need modifications
